House of Lords · 3-2 on the point of law: Lords Hailsham, Cross of Chelsea and Fraser of Tullybelton in the majority; Lords Simon of Glaisdale and Edmund-Davies dissenting. The appeals were nonetheless dismissed.
Facts
Morgan, an RAF officer, invited three junior servicemen home to have intercourse with his wife and told them, as they said, that any protest from her would be pretence. She struggled and protested and they had intercourse with her. The three men were convicted of rape and Morgan of aiding and abetting rape. They said they believed she was consenting. The judge directed the jury that the belief had to be reasonable.
History
The defendants were convicted at trial and the Court of Appeal dismissed their appeals. The House of Lords dismissed the appeals, holding by a majority that the direction on honest belief was wrong in law but applying the proviso because no reasonable jury could have accepted the belief claimed.
Issue
Whether a mistake as to consent must be reasonable to negative the mens rea for rape, or whether an honest but unreasonable belief suffices.
Held
Appeals dismissed. The House held by a majority that an honest belief in consent need not be reasonable, but the convictions stood because the proviso was applied.
Ratio
- The mens rea for rape is intention to have intercourse without consent, which requires either knowledge of non-consent or recklessness as to consent. An honest belief in consent, however unreasonable, negatives that mens rea.
The judgments
Lord Hailsham (majority)
Emphasised that the mental element of rape is an intention to have intercourse without consent. A genuine mistake of fact as to consent, even if unreasonable, means the defendant lacks that intention. The reasonableness of the belief is relevant only to the jury's assessment of honesty.
Key reasoning
- The offence of rape requires proof of an intention to have intercourse without the woman's consent.
- A mistake of fact as to consent, if honestly held, means the defendant does not possess that intention.
- The reasonableness of the belief is not an element of the offence but is evidence from which the jury may infer whether the belief was genuinely held.
- Recklessness as to consent requires the defendant to have foreseen the possibility of non-consent and to have proceeded regardless.
Where it fits in the module
This case is central to Topic 1's exploration of mens rea, mistake of fact and the subjective/objective divide. It illustrates the common law's commitment to a subjective mental element for serious offences, contrasting with the objective recklessness introduced in Caldwell and later rejected in G and R. It also connects to the debate on whether reasonableness should be a legal requirement or merely evidential, a theme recurring in cases such as Cunningham, Majewski and the statutory reforms on sexual offences.
Criticisms
- The subjective test allows a defence based on a fanciful or perverse belief, potentially undermining protection for complainants.
- The distinction between mistake and recklessness can be difficult for juries to apply in practice.
- The decision was seen as too favourable to defendants, prompting legislative intervention in the Sexual Offences Act 2003 which introduced a reasonableness requirement.
